pythonnet and numpy
Hello, As mentioned in the other thread, I have built pythonnet with VS2012 for a 64-bit Python installation and using .NET 4 assemblies. Things seem to work well. However, I just tried to `import numpy` and all hell broke loose... the reason I pursued pythonnet was because I thought it would allow me to use the pure CPython modules without needing to rely on any of the modified versions built for IronPython. Below is the PowerShell output from starting EPD and importing numpy and starting pythonnet python.exe and importing numpy. PS G:\svn\Python\pythonnet\trunk\pythonnet\src\console\bin\Debug> python #should load EPD python Enthought Python Distribution -- www.enthought.com Version: 7.3-2 (64-bit) Python 2.7.3 |EPD 7.3-2 (64-bit)| (default, Apr 12 2012, 15:20:16) [MSC v.1500 64 bit (AMD64)] on win32 Type "credits", "demo" or "enthought" for more information.

That error suggests issues with your path or current directory. Multiple or incompatible dynamic libraries etc. in the path. Generally speaking, pythonnet does work with numpy. Something specific is wrong, loading a dll in a low level manner that msvc is upset. Sent from my iPad On Nov 2, 2012, at 10:55 AM, John Burkhart <jfburkhart.reg@gmail.com> wrote:

Make sure you are installing the correct "bitness" of numpy for your install of python (64-bit to 64-bit, 32-bit to 32-bit). On 11/2/2012 8:42 AM, Bradley Friedman wrote:

There is also the ucs-2 versus ucs-4 binary incompatibility. Though that one usually shows up when you call, not when you bind. But then again, I have only kicked that off on unix. On windows it might show up on bind. Not sure. Does numpy import when run from the exact python you are using python.net with? Sent from my iPad On Nov 2, 2012, at 10:48 PM, "Stephen P.
